/* ============================================================
   Materi Pembelajaran — stylesheet
   ------------------------------------------------------------
   TEMA: MIT School of Engineering (engineering.mit.edu)

   Nilai di blok :root diambil langsung dari stylesheet asli
   mereka (app.css v1.0.3), bukan dikira-kira:

     --c-gray-6  #212326   teks utama
     --c-gray-5  #495056   teks sekunder
     --c-gray-4  #838d95   teks samar
     --c-gray-3  #b8c2cc   garis / border
     --c-gray-2  #dbe1e5   latar blok
     --c-gray-1  #f2f4f8   latar blok terang
     --c-red     #750014   merah MIT (aman untuk teks di atas putih)
     --c-accessible-bright-red #c7000d  tautan / hover
     --c-bright-red #ee0010  aksen dekoratif (garis, kotak)
     --c-green-2 #39c811  --c-yellow-2 #ffe600  --c-blue-2 #2ea3ff

   CIRI BAHASA DESAINNYA (yang membedakan dari tema "startup"):
     - Sudut siku (border-radius 0) pada blok, kartu, dan gambar.
       Hanya tombol yang pill.
     - Tanpa drop-shadow. Pemisah = garis rambut 1px.
     - Label kecil: font mono, HURUF BESAR, letter-spacing lebar.
     - Judul seksi diapit garis merah 1px di atasnya.
     - Hover kartu: teks naik 5px + jadi merah, bukan bayangan.
     - Angka besar pakai font display, line-height rapat.

   Ubah palet hanya di :root.

/* ---------- Parallax: hero + frame gambar ----------
   Prinsipnya sama dengan situs Hermes:
   1. Hero bergeser naik pelan saat halaman di-scroll.
   2. Gambar di dalam frame bergeser ±10% tinggi dirinya sendiri,
      jadi tepi frame tidak pernah kosong walau gambarnya digeser.
   Nilai --py* di-set dari JS; kalau JS mati, semuanya tetap di 0
   dan tidak ada yang rusak.

   CATATAN PENTING (permintaan pemilik situs):
   Elemen awal TIDAK memudar dan TIDAK diblur saat di-scroll.
   Efek blur/fade membuat halaman terasa seperti "full daring" —
   padahal situs ini digitalisasi arsip, jadi yang bergerak hanya
   posisi, bukan kejernihan. Karena itu .hw-hero-fade sekarang
   sengaja dibiarkan netral (opacity 1, tanpa filter).

   Angka scale(1.18) BUKAN hiasan: crop yang tersisa setelah
   pergeseran maksimum adalah (1.18 - 1) / 2 = 7.6% per sisi, dan
   gambar scan sudah diberi bantalan putih 12% per sisi, jadi yang
   terpotong selalu area kosong, bukan teks.

   Cara mengukur margin gambar baru (jalankan sebelum mengganti):
     from PIL import Image; import numpy as np
     a = np.array(Image.open('gambar.jpg').convert('L')); ink = a < 200
     c = np.where(ink.any(axis=0))[0]; r = np.where(ink.any(axis=1))[0]
     h, w = a.shape
     print(c[0]/w, (w-1-c[-1])/w, r[0]/h, (h-1-r[-1])/h)   # harus > 0.076
   Kalau marginnya lebih tipis dari 7.6%, tambahkan bantalan putih dulu
   (ImageOps.expand) dan sesuaikan aspect-ratio frame-nya.            */
